Narrow diode for decoupling from power supplies

Phoenix Contact presents a new diode for power supplies from Uno Power, measuring just 22.5mm wide, and designed to decouple power supplies connected in parallel to increase operational reliability.

The high power density of the power supply units in this range offers the ideal solution for loads up to 100 W, especially in compact control boxes. When used in sensitive applications that require high availability, redundant power supply concepts are recommended. If the power supplies, which are operated in parallel, are also decoupled from the diode, a short circuit at the output of one of the power supply units or in the supply line from the power supply unit to the diode will have no effect on the load.

The diode operates with an input voltage range of 4.5 to 30 V DC and nominal input currents of 2 x 10 A or 1 x 20 A. The module is snapped onto the DIN rail without spacing on either side and operates at ambient temperatures from -25°C to +70°C, making it suitable for industrial use.

Uno Power offers 15 corresponding power supplies with output voltages from 5 to 48 V DC. Their high power density makes them the ideal solution in compact control boxes, where loads of up to 100 W are supplied reliably.

The reduced energy consumption of these power supplies is achieved through low idling losses below 0.3 W and optimised efficiency of over 90%.

The power supplies are available in a choice of three housings measuring 22.5 or 35 or 55 x 90 x 84 mm (width x height x depth) saving space in the control cabinet, thanks to their extremely high power density of 240 W/dm³. The power supplies for 5, 12, 15, 24, and 48 V DC output voltage are available in the 25, 30, 40, 55, 60, 90, and 100 W performance class.
